CARRIAGE-SPRING.

SPECIFICATION forming part of Letters Patent No. 681,094, dated. August 20, 1901*. Application tiled May l0, 1901. Serial lilo.` 59,547. (No model.)

To all whom it may concern: Y

Be it known that I, SAMUEL' R. BAILEY, a

. citizen of the United States, residing at Amesbury, in the count-y of Essex and State ot the following is a specification.

This invention relates to improvements in n n y carriage-springs for vehicles; and it consists in improved means for connecting the ends of the leaf or elliptic springs, as will hereinl after be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure 1 represents a side elevation of a Fig. 2 represents an enlarged top plan view of one of the ends of the upper spring and its connection to the lower spring. Fig. 3 represents a bottom plan view of Fig. 2. Fig. 4 represents a central longitudinal section on the line 4 4, shown in Fig.2. Fig. 5 represents a longitudinal Fig. 6 represents a horizontal section on the line 6 6, shown in Fig. 4. Fig. 7 represents acrosssection on the line 7 7, shown in Fig. 4. Fig. 8 represents a detail top plan view of the upper spring, and Fig. 9 represents a detail top plan viewot' the lower spring.

Similar letters referto similar parts wherever they occur on the different parts ot' the drawings.

springs. l `40I n In Fig. l, A and B represent, respectively, the upper and lower leaves of an elliptic or leaf vehicle-spring, to which are respectively attached the additional leaf-springs a aa and b b b, as is usual in this kind of carriage- One of the springs, preferably the upper one, A, is hooked at its ends at A' for the purpose of receiving the ends of the lower spring B, which ard thus caused to be received in and to bear against the inner portion of the hooks A of the upper spring A, as shown in the drawings.

C is a semicircular (or nearly so) socket,

adaptedto inclose the ends of' the upper and a lower springs A B, as shown, such socket having circular closed end pieces C C made integral with said` socket and serving as abutments for preventing a lateral motion of the respective springs.

In practice I prefer to make on the inner portion of the socket C a pin or projection C, adapted to be received in a perforation A in the upper springr A, as shown, and b y such arrangement the ends of the upper spring A are suitably interlocked with and connected to the sockets C, as shown, thus preventing detachment of said sockets from the ends of the springs.

It' so desired, the ends of the upper spring A may be riveted to the sockets C or otherwise connected thereto Without departing from the essence of my invention.

Integral with or attached to the closed end pieces C C are inwardly-projecting pins Cs C3, adapted to be received in side recesses Bf B on the lower spring for the purpose of holding the said lower spring interlocked relative to the sockets C C and allowing said lower spring to yield relative to the upper one when in use on the vehicle.

For the purpose ot' lubricating the bearing of the end of the lower spring relative to the interior of the hooked end of the upper spring I make on the interior of eachsocke't C a cavity O4, adapted to contain one or more wicks D, wholly or partially inserted in perforations A3 Ag'in the hooked ends of the upper spring A, as shown in Figs. 5 and 8. The said wicks may be suitably charged with any well-known lubricant from time to time as needed.

The invention is very simple in construction and serves as a strong and durable means for yieldingl y connecting the ends of carriagesprings, as hereinabove described.

What I wish to secure by Letters Patent and claim isl. The herein-described elliptic `carriagespring, consisting of an upper and a lower member,`one of said members having hooked ends engaging the straight ends of the other members, in combination with socket-pieces inclosing the ends of said members, said socket-pieces being connected to one of the members and having closed ends, and inwardly-projecting pins on the ends of the socket-pieces, the sides of the member unconnected to the socket-pieces being provided with recesses into which said pins project, substantially as specified. i
